IMPROVEMENT IN WHIRLING TOYS.

Specification forming part of Letters Patent No. 186,255, dated January16, 1877; application filed November 23, 1876.

To all whom it 'may concern:

Be it knownthat I, JAMES H. JENKINS, of the city, county, and State ofNewYork, have invented certain Improvements in Whistling Toys, of whichthe following is a specification:

This invention relates to a whistling toy, to which a whirling motion isgiven by means of a string held in the hand; and it comprises a toy ofthis description constructed with one or more bores or openings,extending entirely through the block or body, tapered to a diminisheddiameter at the center, arranged nearly or quite at right angles to theradius of motion, and provided with a whistle, whereby a peculiarwarbling or whistlingsound is produced as the air passes through thetoy.

The invention also comprises the toy constructed with thesedoubly-tapered bores, ar-

ranged at an angle to each other, and each provided with a whistle,whereby one of the bores is always presented for the direct passage ofair therethrough, and consequently a whistle caused to sound, whateverside ofthe block is foremost in whirling.

The invention further comprises a novel combination, with the blockattached to a suitable cord or string of a peculiarly-constructedwhistle, whereby the air is gathered to the orifice or mouth of saidwhistle in such volume and at such velocity as to insure y the sensitiveaction of said whistle and its clear and musical sounding when the toyis Operated.

Figure l is a side view of a sensitive whistling-toy constructedaccording to my invention, and Fig. 2 is a central transverse section 'lofthe same.

A is a block, which may be of any suitable shape, but which, preferably,is of spherical form. Extended through' block A are two or more holes,openings, or orices, B, these orifices being placed at an angle to eachother, as indicated in the drawings, and each opening being preferablydared from its center outward, as shown more fully in Fig. 2. In thecenter of each opening is placed the whistle C. This whistle comprises acylindric body, a, each end of which is provided with funnel-shaped endsb, at the centers of which are mouths a', which, by the lpassage of airtherethrough, give the whistling or musical sound desired. The block Ais attached by means of a suitable eye or staple or otherwise to astring, (l, which may be of any suitable length.

In the use of the toy, the string is held in the hand with a sufficientlength between the latter and the block A to permit the swinging orrotation of the block circularly around the axis formed by the graspingof the string by the hand,`as aforesaid. Inasmuch as the openings orbores B are placed at an angle to each other, it follows that, whicheverside of the block is foremost, the air will be caused to pass throughone or the other of the said bores or orices, it being, of course,understood that such bores or orifices in their posi tion approach moreor less a right angle to the striu g O when the latteris strainedstraight by the centrifugal action of the block A while being whirled orrotated, as hereiubefore explained. As the block A is thus rotated itspassage through'the air causes a vacuum to he formed behind the same atthe same time that the movement of the said block against the air infront tends to compress the latter, sothat the air passes with avelocity proper tioned to the speed with which the block A is caused tomove into and through the bores` or openings B, and, passing through thewhistle C, causes the same to sound with a whistling or musical noise.

It is to be especially observed that the funnelshaped ends c of thewhistle, converging inm ward to the mouths a. of the latter, gather orcompress the air to the said mouths a', thereby increasing its velocityin passing through such mouths a', and insuring a more sensitive actionof the whistle, the sound or whistling being varied both in tone andpitch, according as the velocity of the air passing through the mouths ais varied ever so slightly. By this means an extremely-sensitive actionof the Whistle and a clear musical and pleasing whistling is obtained. ll

What I claim as my invention is- 1. The herein-described whirling toy,con structed with one or more bores, B, funnelshaped or tapering to adiminished diameter at the center of the block A, arranged at rightangles to the radius vof rotation, and provided with `the,funnel-shapedends b, converging to with a whistle, substantially as and for the themouths a', lche said Whistle being placed purpose set forth. midway in abore or orifice extending through 2. In aJ whirling toy, two or morefnnnelthe block A, substantially as and for the purshaped oroppositely-tapering bores, B, arpose herein set forth.

ranged at an angle to each other, and each .JAMES H. JENKINS. providedwith aJ Whistle, substanizially as and Witnesses: for the purpose hereinset forth. EDWARD HOLLY,
